On consideration of high stability and high accuracy dot alignment at various work distances, it is the best job to operate a 650nm red laser diode module within 5mW to 100mW. Inside 16mm or 26mm diameter metal housing tube, after leaving enough time or space for tube cooling down, it gets good thermal emitting and highly stable red dot projection in continuous use.
This 650nm red dot laser applies a qualified glass coated lens inside metal housing tube. It generates high transmittance and high intensity red laser light, and highly clear red dot projection, without any effect by moisture or dust as well. Within long extending distance of 25 meters, after correct use of output power and freely adjusted dot diameter, it achieves high level of accuracy dot alignment for all occasions effectively.
Applications: industrial precise dot alignment, drilling system, laser marking, laser engraving and high tech etc
